GEORGE HOWARD NEIDLINGER, OF BROOKLYN, NEIV YORK.

NIPPLE.

SPECIFICATION forming part of Letters Patent N 0. 577,199, dated February 16, 1897. Application filed November 18, 1895. Serial No. 569,309. (No model.)

To all whom, it may concern:

Beit known that I, GEORGE HOWARD N EID- LINGER, a citizen of the United States, resid- 1 ing in Brooklyn, in the county of Kings and State of New York, have invented a new and Improved Sucking-Nipple, of which the following is a specification.

My invention relates to an improvement in sucking-nipples; and it consists of a rib or series of ribs running in a spiral direction on the inside of the nipple, formed integrally therewith, and made before the rubber is vulcanized. The ribs, acting as a spring, serve to keep the nipple normally extended and prevent the collapse of said nipple, the ribs being formed to cross each other at an angle when pressed together, leaving space between the ribs for food to flow from the bottle.

In the drawings, Figure 1 is a side elevation of the nipple. Fig. 2 is a vertical transverse section, and Fig. 3 is a horizontal section taken on line a; as in Fig. 1.

A is the nipple, made'of soft rubber and adapted to be clasped over the neck of a nursing-bottle.

B B are the inwardly-projecting ribs or 001'- rugations, running spirally in a longitudinal direction and acting as a spring or springs which tend to distend the bulb of the nipple.

The nipple is made in one piece with the ribs or corrugations constituting part of the same, all being formed in a suitable mold before the rubber is vulcanized.

It is obvious that I may employ diagonal ribs which are not spiral. Therefore I do not limit myself strictly to the form shown.

In the top of the nipple are formed one or more holes 0 for the escape of food.

Vhat I claim as new, and desire to secure by Letters Patent, is-

A soft nipple for nursing-bottles, provided with a perforation at the top adapted to be clasped over the vent of a nursing-bottle, and provided in the inside with ridges curved at the ends in opposite directions, the ridges on opposite sides being arranged to cross each other at an angle, whereby the complete collapse of the nipple is prevented, substantially as described.

GEORGE HOWARD NEIDLINGER.
